The gospel roots of rock have been discussed in depth. You'll find a lot of information on the subject online.
It's worth pointing out that there's a marked division within the genre between Black gospel music (which is the tradition rock-'n'-roll has its roots in) and "Southern" or "Christian" gospel which is tightly interrelated with southern evangelical fundamentalism, and is (not surprisingly) both overwhelmingly white and extremely conservative musically.
